> I found that when using NumberUtils【org.apache.commons.lang3.math.NumberUtils.isNumber(version3.4)】
isNumber method the following phenomenon, 
> when the parameter is 1.0 is true, but when the parameter is 0.1 is displayed is false.
> When I use 0.1 as the parameter tuning isNumber method, 
> view the source code in the method of the method of line 1370 discovered a problem.
> When the analytical parameter is ". ", this time the chars [I] value is 46, direct return
false.
> I think to do so is not very reasonable, please give me your guidance.
